This is a follow up question to another question I made earlier.
I put some of this information into my own notes just so I can get my head around this.
So just to clarify. Does the Woodward Hoffman rule given below only apply to ground state reactions, thus the rule cannot be applied to the above reaction scheme because one of the components is in an excited state?
A ground-state pericyclic change is symmetry-allowed when the total number of (4n+2)s and (4n)a components is odd.
